Tips for removing rusted bearings on a JP Maxees

Enter a word or two to search the forum section and click the Search Forum button.

Hi,

 

does anyone have any tips for removing and replacing rusted bearings?

The rust was very bad so I broke and removed the metal  on the actual bearings but the balls are all still in place and there doesn't seem to be enough room to remove them?

Is brute force the only way?

 

Cheers,

 

Karl

oxy acetylene or oxy propane heating helps a heck of a lot in certain cases as well as penetrant spray.

if you're undertaking restorations of a few machines, it's worth considering investing in a gas welding and cutting kit and some lessons if you're not familiar with gas work. I swear by it when it's available. At the mo, no gas, so using a mapp gas blow torch which doesn't deliver as much heat. the annoyance is a wide flame. for getting into bearing reliefs, a narrow flame with plenty of heat works best rather than an exposure flame that spreads over a wide area.

Hi,

I have a Rothenberger MAPP torch and use the optional pointed flame nozzle that they sell as an accessory. I think that you will find that this will solve your problem the flame is very controllable using this nozzle.

If the bearing is off the shaft but stuck in the carrier/holder you can use a small sharp (ground to a chisel point) cold chisel  to cut out the ball carrier. It is then usually possible  to manoeuvre  the balls to one side and release the inner race. If you are then left with the outer race stuck in the holder but with no room to punch it out from behind you can use one of the methods posted on this forum for removing a AutoCertes/Marquis clutch spigot bearings.
